Advertisers don't like crazy.

After a long list of bat-shit-crazy things Glenn Beck has said, the conservative talk show host has apparently pushed advertisers too far.

So, which crazy straw broke the camel's back?

Joking about poisoning Nancy Pelosi? No.

Screaming/shrieking at a radio caller who disagreed with him? No.

Beck actually saying he believed our mixed race president was a racist? Yahtzee!

Ad Age has picked up on the story that many online discussion boards and aggregators, like Reddit, have been talking about for weeks.

ColorofChange.com has been leading the calls for a boycott of GB's prime-time show on Fox News because of his "racist" comment. So far, 36 advertisers have demanded that their ad spots won't appear on Beck's show.

And these aren't no-name companies like the Extenze male enhancement guys but big wigs like Wal-Mart, Procter & Gamble, S.C. Johnson, Clorox, and Sprint.

Clorox has gone as far as to say not only will they be pulling all future ads from GB but they are also avoiding all "inflammatory" political talk shows, right or left, for the foreseeable future.

This raises an interesting problem for advertisers.

The political talking heads like Beck, Hannity, O'Reilly and Olbermann have made a name for themselves by being incendiary. Which is bad. But they have the highest ratings on cable news. Which is good. So what's an ad buyer to do? Can't be sure but this consumer is hoping they'll choose the high road.
